Dependency-based targeted attacks in interdependent networks

Modern large engineered network systems normally work in cooperation and incorporate dependencies between their components for purposes of efficiency and regulation. Such dependencies may become a major risk since they can cause small-scale failures...

Exponential volume dependence of entropy-current fluctuations at first-order phase transitions in chemical reaction networks

In chemical reaction networks, bistability can only occur far from equilibrium. It is associated with a first-order phase transition where the control parameter is the thermodynamic force. At the bistable point, the entropy production is known to be...

Glassy Dynamics and Memory Effects in an Intrinsically Disordered Protein Construct

The relaxation of stretched intrinsically disordered proteins reveals glassy dynamics and memory effects at the single-molecule level.

What If Planet 9 Is a Primordial Black Hole?

While astronomers look for a ninth planet to explain orbits in the outer Solar System, a duo explores the possibility that the mystery object is a primordial black hole.

The physics of climate variability and climate change

This article presents a comprehensive survey of the fundamentals of climate dynamics. Recent developments in dynamical systems theory, as well as in random processes and statistical mechanics, have created a common framework for physicists and...

Intriguing effects of underlying star topology in Schelling's model with blocks

We explore the intriguing effects of the underlying star topological structure in the framework of Schelling's segregation model with blocks. The significant consequences exerted by the star topology are both theoretically analyzed and numerically...

Stochastic Time Evolution, Information Geometry, and the Cram\'er-Rao Bound

The information encoded in a stochastic physical system sets a limit on how fast any thermodynamic observable can change, thus making a connection between the abstract concept of information and physical quantities such as heat and work.

Arrow of time across five centuries of classical music

This paper considers classical music pieces as stochastic trajectories and explores the extent to which these display statistical time irreversibility, i.e. whether a preferential time arrow emerges with an associated entropy production. Since 1/f...

Deep learning and AdS/QCD

We propose a deep learning method to build an AdS/QCD model from the data of hadron spectra. A major problem of generic AdS/QCD models is that a large ambiguity is allowed for the bulk gravity metric with which QCD observables are holographically...

Autonomous Maxwell's demon in a cavity QED system

This work exploits a cavity QED system to investigate the connection between energy, information and the thermodynamic arrow of time in the quantum realm. The paper proposes an autonomous scheme of the Maxwell's demon with a single Rydberg atom and...

Anomalous epidemic spreading in heterogeneous networks

Epidemic spreading in heterogeneous networks has attracted great interest in recent years. To capture the significant effect of residence of individuals on epidemic spreading, we consider herein a simple susceptible-infected-susceptible model with...

Statistical analysis of edges and bredges in configuration model networks

A bredge (bridge-edge) in a network is an edge whose deletion would split the network component on which it resides into two separate components. Bredges are vulnerable links that play an important role in network collapse processes, which may...

Scale-dependent measure of network centrality from diffusion dynamics

The authors use intrinsic properties of diffusion dynamics on graphs to define a scale-dependent node centrality measure. The time horizon of the diffusion plays the role of a natural scale factor. As the diffusion increasingly probes the...

Taxonomies of networks from community structure

The study of networks has become a substantial interdisciplinary endeavor that encompasses myriad disciplines in the natural, social, and information sciences. Here we introduce a framework for constructing taxonomies of networks based on their...

Supernova-Produced $^{53}\mathrm{Mn}$ on Earth

For the time period from 1.5 to 4 Myr before the present we found in deep ocean ferromanganese crusts a $^{53}\mathrm{Mn}$ excess concentration in terms of $^{53}\mathrm{Mn}/\mathrm{Mn}$ of about...
